Thanks everyone!

Discount tire is giving me $300 for my current RFTs (with 8K miles) and $100 of rebate if I purchase the PSS. Now I'm thinking to swap out the RFTs with PSS sometime next week.

Just bought my car a week ago. Dealer demo 2014 320i and even before I picked it up I already ordered 5 Kumho Ecsta PA31s. I only drove the car a few days with the stupid RFTs on and overall the regular tires are better, hands down. Also you can sell your RFTs and use the money to pay for your regular tires and then some.

Edit: the 5th Kumho is a spare that I'll just keep in the trunk...I am NOT a fan of not being given the option of a spre like my '05 325XI had.

I just got my Conti RFTs replaced with Michelin PSS and both the ride quality and noise level have improved noticeably. I realized it the day after I got the replacement when I was driving to work on the road I take everyday and know all the bumps well. I was noticing that the bumps are not that harsh anymore, at first was wondering what's going on, maybe I lost tire pressure that softened the tires and hence they absorb the bumps more, but then I realized that I had the new tires on. :-)

As far as repair kit is concerned I bought the AAA pump kit on Amazon for like $25, I think that should do it, I don't think the slime thing is much of a use. In 90% of the cases when you get a flat it's because of a nail or screw and the air is leaking slowly, so if you pump the leaky tire up to 40 PSI (or a little bit above) you have several hours till the pressure drops below 32 PSI, where it would be recommended to re-pump again, but by then you should have gotten home or found a repair shop already. If there is a bigger cut, the slime wouldn't help either, just a spare tire.

i despise RFTs. Giving up too much performance/comfort just to replace hassle of carrying and changing a spare tire (which is minimal) On a Benz I rented once, it came with a deflated spare and a pump..didn't take up a lot of room...why couldn't BMW use that instead?

[karoll]

i recommen to find a tire shop, where you can talk with an expert about the best desicion in tires for your car, its better to talk with a mechanical certified, because they can give you the best advice. Good luck

Does anyone know how to store run flat tires when being used as a back up set?

[buckybadger]

I have ordered the Michelin PSS and will be installing it this coming weekend. I am looking at the BMW Mobility Kit online but it seems to be pricey:

Also, anyone tried the stop 'n go stuff?

Anyone knows where I can find a better price?

Thanks!

Go for the Slime 70005 Safety Spair kit which is the same concept as BMW Mobility Kit but at a reasonable price (selling at $40 or even less).

portable air compressor, this thing pumps in air quick.

i have this in the compartment of my trunk along w/ a jack, tire wrench, impact driver, tire repair kit (plug in type), a box of gloves, flashlight, and a vest (for night time visibility.
in short, i assembled my own tire repair kit.

A bit late to the party but I changed from factory Goodyear Eagle F1 Asymmetric 2 (good reputation tyres) to Michelin PSS, and very happy:
- Much more steering feel (steering is lighter too, while it seems to give a lot of detailed feedback on the road surface)
- Much better at absorbing bumps (no more "clunks" when going over a bump - they love these speed bump here in France, we have one every 500m)
- Not necessarily directly related to RFT / non-RFT (debatable...), but the stopping power is *amazingly* better, I had to stop on a very short distance yesterday, with the RFT the ABS kicked in very soon, the tyre was slipping more easily; with the PSS none of that, even if i was standing on the brake pedal, the full power of the M Perf brakes was absorbed by the tyres without a hint of a slip, I was absolutely thrilled. Excellent for performance and security.

I bought this compact kit in the event of a puncture:

Just had a flat with my non-runflat Conti DWS and wanted to share my thoughts on what you should carry with you if you do decide to go non-runflat:

1/ Small compressor. Don'y rely on just the air that a slime can might have. This will also help you identify the hole. There are a ton of small compressors out there that will run off the 12V for about $40-50.

2/ Tire plug kit. This saved the day for me when the slime did not work.

3/ Slime kit. I would only use this as a last resort and first use the compressor to help identify the location of the leak and then try to plug it (I tried Slime first and it did not work, thus ruining a tire that might have been salvageable).

4/ Tow service. This is a must BUT I also strongly recommend the items above. Having those turned what could have been a 4 hour ordeal for me into a 30 minute repair.

Hope this helps.
